This text offers a comprehensive presentation of topics in the field of soil mechanics and foundations. It offers a perfect balance of theory and applications for engineers and non-engineers, while also providing readers involved in architecture and construction-related programs with present-day, state-of-the-art information as accepted by, and conveniently used by, the construction industry. Features of this new edition include: New material on residual soil formations and soil classification. Updated information relating effects of seismic activity on soil conditions, including recent Federal Emergency Management Agency (FEMA) and National Earthquake Hazards Reduction Program (NEHRP) provisions for structures (requirements being incorporated into the revisions of regional building codes). Enhanced coverage of the concepts and procedures for site improvements. New material on basic geology and the formation of soil deposits, which affects the mechanics of soil behavior. Discussion of data and design criteria for many practical applications involving soils, including site planning and site improvement as well as material for foundation design and construction.
